Interactive: Psychiatric Prisons See More Violence

Texas psychiatric facilities report the most violent incidents per inmate, according to data from the Texas Department of Criminal Justice analyzed by The Texas Tribune. The Tribune reviewed the number of violent incidents reported at more than 90 prison facilities across the state from 2006 to 2012, examining the number of incidents, ranging from serious assaults and hurling of bodily fluids — chunking — to uses of force by officers.

Among the five units with the most such incidents on a per-capita basis were the state's three psychiatric prisons. Also among the top five was the William P. Clements Unit in Amarillo, where more than half of the inmates are mentally ill. The Clements Unit reported more than 6,600 violent incidents between 2006 and 2012, the most of any facility operated by TDCJ during the time period.
